QA1 68-72 GM X-Body Handling Kit Level 3

QA1's Level 3 Handling Kit is the most aggressive suspension package they offer for 1968-1972 GM X-body cars, covering the Chevrolet Chevy II, Nova, and Pontiac Ventura. This is a complete front and rear suspension replacement aimed at owners who want track-day capability without giving up street comfort, and it starts with 4-way adjustable MOD Series coilovers that let you swap valve packs in minutes to go from autocross settings to a comfortable street ride.

Up front, QA1's tubular control arms are among the lightest available for this platform. Paired with the MOD coilovers and a tubular front sway bar, the front end responds quickly and predictably. You get 0 to -2 inches of front ride height adjustment, so dialing in the stance is straightforward. Out back, the tubular 4-link provides +2 to -3 inches of rear ride height adjustability and is designed to work with both standard tubs and mini-tubs, clearing up to 315mm tires when mini tubs are installed.

Installation is a mix of bolt-on and light fabrication. The front suspension bolts in completely, while the 4-link requires minimal welding. No modifications to the floor pan are needed, and adjusting ride height, pinion angle, or wheelbase after installation requires just a few tweaks with no link removal. QA1 includes a spanner wrench with the kit, and they strongly recommend adding their subframe connectors for the best results.

The 4-way adjustable MOD shocks are the real advantage here. Being able to change compression and rebound settings for different events, from autocross to road courses to speed stop challenges, means you can tune the car to the situation rather than settling on a single compromise setting. QA1 manufactures these components in the USA. Welding is required for the rear installation, and wheel and tire fitment should be verified on the vehicle.
